Eric can you explain it to me why is the attribute "physical" appropriate
here? I did a quick grep for "Physical Subchannel" only turned up hits
in vfio-ccw.

My best guess is that "physical" was somehow intended to mean the
opposite of "virtual". But actually it does not matter if our underlying
subchannel is emulated or not, at least AFAIU.
